1 Claim.

This invention relates to new and useful improvements in anti-slippingdevices adapted to be worn on shoes.

The principal object of the present invention is to provide ananti-slipping device which can be readily attached to the heel portionsof boots or shoes to prevent slipping on ice or other slippery surfaces.

Other important objects and advantages of the invention will becomeapparent to the reader of the followingv description.

In the drawing:

Figure 1 represents a top plan view of the device.

Figure 2 is a side elevational view of the device applied to a shoeheel.

Referring to the drawing wherein like numerals designate like parts, itcan be seen in Figure 2, that numeral 5 denotes a shoe upper whilenumeral 6 denotes a shoe heel.

The anti-slipping device is generally referred to by numeral 1 andincludes an elongated strip of flexible metal denoted by numeral 8,which is preferably bent to a U-shape and which at its lower edge isformed with inwardly disposed tongues 9, preferably three in number,distributed as substantially shown in Figure 1.

The lower edge of the strip 8 is further provided with depending taperedspurs I0, preferably four in number and these are adapted to bite intoice or other slippery surfaces to prevent slipping.

It is preferable that the device be substantially longer than the lengthof an average shoe heel and is formed with openings II at its endportions to receive a bolt l2. This bolt has a head a at one end and isthreaded at its opposite end as at b to accommodate a winged nut l3.

5 The device is applied to a shoe with the tongues 9 bearing against thebottom of the heel. With the device in this position, the nut I3 istightened on the bolt I2 to firmly clamp the strip 8 against the sidesof the heel 6.

10 While the foregoing specification sets forth the invention inspecific terms, it is to b understood that numerous changes in theshape, size and materials may be resorted to without departing from thespirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

An anti-slipping device for shoe heels comprising a U-shaped flexiblemember formed from an an elongated strip of metal and provided with aseries of polygonal openings in each of its end portions, spurs integralwith and depending from the lower edge of the U-shaped member, a boltdisposed through a desired aligned pair of the openings and equippedwith a nut whereby the device can be clamped against the shoe heel, saidbolt having a polygonal shank portion adjacent its head fitting anopening of one end portion to hold the bolt against turning, andintegral tongues projecting inwardly from the lower edge of the fiexiblestrip for disposition flatly against the bottom of a shoe heel.
